A gentle Korean retinol serum specifically designed for retinol beginners and sensitive skin — Blue Bio-Retinol delivers the pore-refining and anti-aging power of traditional retinol with significantly less irritation. Clinically proven to improve 10 key pore concerns including pore size, depth and volume, while visibly smoothing skin texture and fading dark spots. Thoughtfully formulated so that even those who have previously reacted to retinol can finally use it.

• Blue Bio-Retinol (Encapsulated Retinol + Bio-Based Retinol) — a dual-retinol system that combines gentle bio-based retinol with encapsulated pure retinol for slow, controlled release; this delivery method minimizes irritation, redness and peeling while still delivering the full pore-tightening, texture-smoothing and fine-line-reducing benefits of traditional retinol
• Niacinamide 10% — one of the highest niacinamide concentrations available in a serum; enhances the effects of the blue retinol by improving skin texture, brightening dark spots and promoting a visibly smoother, healthier-looking complexion — while also helping to buffer any sensitivity from the retinol
• Clinically Tested on 10 Pore Concerns — proven to improve pore size, depth and volume, as well as pore tightness and overall skin barrier strength; a comprehensive clinical validation that covers the full spectrum of pore-related concerns

Apply after toning as part of your PM routine. Start 2–3 nights per week and increase frequency as skin adjusts. Suitable for all skin types including sensitive. Always follow with SPF the next morning. 50ml.
